DESCRIPTION
The SC1158 is a low-cost, full featured, synchronous voltage-mode controller
designed for use in single ended power supply applications where efficiency is
of primary concern. Synchronous operation allows for the elimination of heat
sinks in many applications. The SC1158 is ideal for implementing DC/DC
converters needed to power advanced microprocessors such as Pentium® ll and
K6-2. Internal level-shift, high-side drive circuitry, and preset shoot-thru
control, allows for use of inexpensive N-channel power switches.
SC1158 features include an integrated 4-bit VID DAC, temperature compensated
voltage reference, triangle wave oscillator, current limit comparator,
frequency shift over-current protection, and an internally compensated error
amplifier.
The SC1158 operates at a fixed 140KHz, providing an optimum compromise between
efficiency, external component size, and cost.
FEATURES
• Low cost / full featured
• Synchronous operation
• 4 Bit VID DAC programmable output (1% tolerance)
• Meets Intel VRM8.2 (Pentium® II) high range
• 1.5% Reference
APPLICATIONS
• Pentium® II, K6-2 Core Supplies
